Recently, using a numerical surface cooling approach, we have shown that highly energetic discrete breathers (DBs) can form in the stiffest parts of nonlinear network models of large protein structures. In the present study, using an analytical approach, we extend our previous results to low-energy discrete breathers as well as to smaller proteins. We confirm and further scrutinize the striking site selectiveness of energy localization in the presence of spatial disorder. In particular, we find…

Discrete breathers in a realistic coarse-grained model of proteins
The combination of these two nonlinear effects may provide a ready means for remotely controlling local conformational changes in proteins and develop as energy-accumulating centres following perturbations even at distant locations.
Breather-mediated energy transfer in proteins
In this paper we investigate how energy is redistributed across protein structures, following localized kicks, within the framework of a nonlinear network model. We show that energy is directed
Nonlinear excitations match correlated motions unveiled by NMR in proteins: a new perspective on allosteric cross-talk
The calculations provide a novel quantitative tool to predict fold-spanning dynamical pathways of correlated residues that may be central to allosteric cross-talk in proteins, and speculate that transient energy redistribution among the vibrational modes in a protein might favor the emergence of DB-like bursts of long-lived energy at hot-spot sites with lifetimes in the ns range.
Long-range energy transfer in proteins.
It is shown, within the framework of a coarse-grained nonlinear network model, that energy in a protein can jump from site to site with high yields, covering in many instances remarkably large distances.
Low energy nuclear reactions driven by discrete breathers
A new mechanism of LENR in solids is proposed, which is based on the large amplitude anharmonic lattice vibrations, a.k.a. intrinsic localized modes or discrete breathers (DBs). In particular, so
Protein dynamics studied by coarse-grained and atomistic theoretical approaches
The main conclusions of this thesis are that the local topology of proteins, not only determines shapes but dynamics, and long-range contact dictate the equilibrium between different motions, which can shift this equilibrium and affect protein functions, causing disease.
Effect of Discrete Breathers on the Specific Heat of a Nonlinear Chain
It is concluded that DBs affect specific heat of the nonlinear chain, and for the case of hard-type (soft-type) anharmonicity, they reduce (increase) the specific heat.
Nuclear catalysis mediated by localized anharmonic vibrations
In many-body nonlinear systems with sufficient anharmonicity, a special kind of lattice vibrations, namely, Localized Anharmonic Vibrations (LAVs) can be excited either thermally or by external
Time evolution of localized solutions in 1-dimensional inhomogeneous FPU models
Abstract We study energy localization in a quartic FPU model with spatial inhomogeneity corresponding to a site-dependent number of interacting neighbors. Such lattices can have linear normal modes


Discrete Breathers
We present a new method for proving the existence of Discrete Breathers in translationally invariant Hamiltonian systems describing massive particles interacting by a short range covex potential
Discrete breathers in nonlinear network models of proteins.
It is shown that spontaneous localization of energy occurs generically and is a site-dependent process, suggesting that nonlinear phenomena may play an important role in enzyme function, allowing for energy storage during the catalytic process.
Discrete breathers in a polyethylene chain
The existence of discrete breathers or intrinsic localized modes (localized periodic oscillations of transzigzag) is shown. In the localization region periodic contraction-extension of valence
Dimension dependent energy thresholds for discrete breathers
Discrete breathers are time-periodic, spatially localized solutions of the equations of motion for a system of classical degrees of freedom interacting on a lattice. We study the existence of energy
